Back to Traditional Chinese Medicine (TCM)What an online TCM visit is
An online visit means a Traditional Chinese Medicine practitioner talks with you by video, phone or message instead of in a clinic. Some practitioners also sell herbal products through the same service. This page is information only. It does not tell you to use or avoid any service, and it does not replace care from your own doctor.What can and cannot be done remotely
In-person TCM visits normally include questions, looking (including the tongue) and touching (including the pulse). See your first TCM visit and the tongue and pulse for how those steps work. Online, the questions and conversation carry over easily. The hands-on parts do not.| Part of the visit | Remote status | What research found | Strength |
|---|---|---|---|
| Health history and questions | Works by video or phone | Not studied here | Not assessed |
| Tongue by photo or video | Possible, with limits | In one study 17 clinicians compared smartphone images with direct inspection and agreement was good to very good for most coating features [1] | Promising but limited |
| Tongue, between different practitioners | Variable | Agreement between raters was moderate for coating and fair for color and other body features [1]; an earlier study of standardized images found rater agreement generally low [2] | Insufficient evidence |
| Pulse | Practitioners feel it by hand | Research has studied it as a manual method at the radial artery [3]; a review found acceptable agreement only with clearly defined methods and poor agreement where terms were unclear [3] | Insufficient evidence |
| Overall pattern diagnosis | Not specific to remote | A review found tongue diagnosis shows considerable variability and pattern diagnosis has not shown high reliability [4] | Insufficient evidence |
The tongue findings come from studies of image quality and rater agreement. They do not show that online care leads to better or worse health outcomes. For those outcomes, Proper evidence not found: we searched PubMed for trials and reviews of TCM telehealth and found nothing usable.
Reading the pulse needs touch. That is our reading of how it is studied, not a finding from a source we read about video visits.
Before you book
- Ask the practitioner which state or country they are licensed in, and check that license with the regulator. California's board advises checking a license, understanding the fee, being satisfied that communications are confidential, and knowing the risks and benefits of telehealth. [6]
- Ask how they handle emergencies and what they will not treat online.
- Tell the practitioner everything you take. Some herbal products can interact with prescription medicines. [7]
- Tell your doctor about the visit. See telling your doctor about TCM.
Buying herbs after an online visit
Dietary supplements in the United States are not approved for safety and effectiveness before sale. [8] Some Chinese herbal products have been found to contain undeclared drugs, heavy metals or the wrong herbs. [9] The NHS says not to buy unlicensed herbal medicines online because they may not be safe. [10] Read buying Chinese herbs safely and red flags in TCM practice first.When not to rely on a remote visit
Do not use an online visit to replace or delay conventional care. [9] Chest pain, trouble breathing, sudden weakness, severe bleeding or thoughts of self-harm need emergency care. In the US call 911, or 988 for mental health crises. Never stop a prescribed medicine on a remote practitioner's advice. [10]Frequently asked questions
Can a practitioner diagnose by video?
They can ask questions and look at your tongue on camera. Research on smartphone tongue images found good agreement for coating features but only fair agreement between raters on color. [1]
Can the pulse be checked online?
Pulse assessment is a hands-on method and the research we read studied it at the wrist artery in person. [3]
Does an out-of-state practitioner need a license where I live?
Often yes. California's board says people giving acupuncture services to people in California are generally required to be licensed there. [6] Rules differ by state, so check yours.
Are herbs bought online after a consultation safe?
Not automatically. Some products have contained undeclared drugs or heavy metals. [9] Ask a pharmacist before taking any herbal medicine alongside other medicines. [10]
Is TCM telehealth proven to work?
Proper evidence not found. We looked for trials and reviews of TCM telehealth and found nothing usable.

Licensing across states
The one regulator statement we could read is from California. Its acupuncture board said the state's law does not specifically prohibit or sanction telehealth for acupuncture. [6] It also said that people who give acupuncture services to people in California are generally required to be licensed in California. [6] It told licensed practitioners serving people in other states to check that state's telehealth laws. [6] That statement dates from the COVID-19 period, and rules change.
Proper evidence not found: we found no regulator source we could read that explains how remote herbal consultations are treated in each state. Herbal advice may fall under different rules from acupuncture. Check your own state's board.
